Description

Technical field [0001] The invention relates to the technical field of photoelectric testing, in particular to a cold trap device. Background technique [0002] When performing photoelectric testing of samples, it is very important to characterize the properties of samples in a low-temperature environment. Directly lowering the temperature of the samples will cause a large amount of condensation or freezing at the samples, making it impossible to carry out photoelectric tests. In particular, if there is no atmosphere isolation near the sample, gas molecules will act as a heat transfer medium to conduct heat conduction to the low-temperature sample from the surrounding temperature, and the temperature cannot be lowered. Therefore, heat conduction isolation and water vapor isolation are the key to achieving low temperature testing. At present, since the low-temperature refrigeration equipment of different optoelectronic test platforms cannot be used universally, it is necessary to...
